2009 GMC ACADIA low oil pressure

Checking Things
Under the Hood
{CAUTION
An electric fan under the hood
can start up and injure you even
when the engine is not running.
Keep hands, clothing, and tools
away from any underhood
electric fan.
{CAUTION
Things that burn can get on hot
engine parts and start a re.
These include liquids like fuel, oil,
coolant, brake uid, windshield
washer and other uids, and
plastic or rubber. You or others
could be burned. Be careful not to
drop or spill things that will burn
onto a hot engine.
Hood Release
To open the hood, do the following:
1. Pull the hood release handle with
this symbol on it. It is located
under the instrument panel
on the driver’s side of the vehicle.
2. At the front of the vehicle, pull up
on the center of the hood, and
push the secondary hood release
to the right.
3. After you have partially lifted the
hood, gas struts will automatically
take over to lift and hold the
hood in the fully open position.Before closing the hood, be sure all
ller caps are on properly.
Pull the hood down to close. Lower
the hood until the lifting pressure of
the strut is reduced. Then allow the
hood to fall and latch into place
under its own weight. Check to make
sure the hood is closed. If the hood
does not fully latch, gently push the
hood down at the front and center
of the hood until it is completely
latched.

Engine Oil
Checking Engine Oil
It is a good idea to check the
engine oil every time you get fuel.
In order to get an accurate reading,
the oil must be warm and the
vehicle must be on level ground.
The engine oil dipstick handle
is a yellow loop. SeeEngine
Compartment Overview on
page 5-10for the location of
the engine oil dipstick.
1. Turn off the engine and give the
oil several minutes to drain back
into the oil pan. If you do not
do this, the oil dipstick might
not show the actual level.2. Pull out the dipstick and clean
it with a paper towel or cloth,
then push it back in all the way.
Remove it again, keeping the
tip down, and check the level.
When to Add Engine Oil
If the oil is below the cross-hatched
area at the tip of the dipstick,
add at least one quart/liter of the
recommended oil. This section
explains what kind of oil to use.
For engine oil crankcase capacity,
seeCapacities and Specifications
on page 5-96.
Notice:Do not add too much oil.
If the engine has so much oil
that the oil level gets above the
cross-hatched area that shows
the proper operating range,
the engine could be damaged.
Service and Appearance Care 5-11

Rinse the vehicle well, before
washing and after to remove all
cleaning agents completely. If they
are allowed to dry on the surface,
they could stain.
Dry the nish with a soft, clean
chamois or an all-cotton towel to
avoid surface scratches and
water spotting.
High pressure car washes may
cause water to enter the vehicle.
Avoid using high pressure washes
closer than 12 inches (30 cm) to
the surface of the vehicle. Use of
power washers exceeding 1,200 psi
(8 274 kPa) can result in damage or
removal of paint and decals.
Cleaning Exterior
Lamps/Lenses
Use only lukewarm or cold water, a
soft cloth and a car washing soap to
clean exterior lamps and lenses.
Follow instructions underWashing
Your Vehicle on page 5-84.
Finish Care
Occasional waxing or mild polishing
of the vehicle by hand may be
necessary to remove residue from
the paint nish. Approved cleaning
products can be obtained from
your dealer/retailer.
If the vehicle has a basecoat/
clearcoat paint nish, the clearcoat
gives more depth and gloss to the
colored basecoat. Always use waxes
and polishes that are non-abrasive
and made for a basecoat/clearcoat
paint nish.
Notice:Machine compounding
or aggressive polishing on a
basecoat/clearcoat paint nish
may damage it. Use only
non-abrasive waxes and polishes
that are made for a basecoat/
clearcoat paint nish on the
vehicle.Foreign materials such as calcium
chloride and other salts, ice melting
agents, road oil and tar, tree sap,
bird droppings, chemicals from
industrial chimneys, etc., can
damage the vehicle’s nish if they
remain on painted surfaces. Wash
the vehicle as soon as possible.
If necessary, use non-abrasive
cleaners that are marked safe for
painted surfaces to remove foreign
matter.
Exterior painted surfaces are
subject to aging, weather and
chemical fallout that can take
their toll over a period of years.
To help keep the paint nish looking
new, keep the vehicle garaged or
covered whenever possible.
